YAML 1.2. Duplicate keys and unsupported numeric values are rejected.
Convert configurations between JSON and YAML
Choose a conversion direction and paste your configuration. JSON objects become YAML mappings and arrays become sequences. In the other direction, the result is formatted JSON. The converter rejects some values that cannot be represented safely, including non-finite numbers and integers that exceed safe conversion limits.
Are YAML comments preserved in JSON?
No. JSON has no comment syntax. Conversion keeps the configuration data rather than its comments.
What should I do if a large integer is rejected?
Use a quoted string if that matches the format your application expects. Rejecting the conversion prevents silently rounding the value.
